Answer:
9.76m²
Step-by-step explanation:
The area of the square is
where s=8m is the side length.
This means that:
The area of a circle is
From the diagram, the diameter is 8m.
This means that the radius is
The area of the circle then becomes,
The area of shaded region is area of square minus area of circle.
Answer:
The answer is 25 miles
Step-by-step explanation:
Answer:
6 packages B
7 packages A
Step-by-step explanation:
let the number of packages A be a and the number of packages B be b
Total number of packages is 13;
Thus;
a + b = 13 •••••(i)
Total package a cost is 18(a) = 18a
Total package b cost is 22(b) = 22b
Total of both is 258
18a + 22b = 258 •••••••(ii)
From i, a = 13-b
Put this in equation ii
18(13-b) + 22b = 258
234-18b + 22b = 258
4b = 258-234
4b = 24
b = 24/4 = 6
since;
a + b = 13
a + 6 = 13
a = 13-6
a = 7
M < E = 180 - 35 - 43 = 102
m< A = 180 - 102 - 18 = 60 degrees Answer
